AERATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 507,392, dated October 24, 1893. Application tiled December 12.J 1892. Serial No. 454,914. (No model.)

To all whom it may concern.-

Be it known that I, BENJAMIN F. TATMAN, a citizen of the United States, anda resident of Owensborough, in the county of Daviess and State of Kentucky, have invented certain new and useful Improvements in Aerati ng Apparatus; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawing, which forms a part of this specification.

My invention relates to apparatus for carbonating liquids and its object is to provide a continuous sight feed carbonatin g fountain in which the liquid and the carbonio acid gas used for carbonating the same are thoroughly and intimately commingled together in an efiicient manner.

The invention consists in the novel construction and combination of parts hereinafter fully described and claimed.

The accompanying drawing represents a sectional elevation of an apparatus constructed according to my invention.

In the said drawing the reference numeral 1 denotes a tub or vessel of wood or other material supported upon legs 2, and provided with a faucet 3. Located vunderneath this tub is a receptacle or fount 4, of any suitable material and construction and provided with pipes 5, by which the contents of the same maybe drawn for bottling and a pipe 5fh leading to a soda fountain as will hereinafter more fully appear. Located in this fount 4, is a step bearing 6, in which is journaled the lower end of a pipe 7, provided with a number of apertures 8. This pipe extends up through the bottom of tub 1, where it communicates with a cooling vessel10, and is provided with a perforated cover 7 a. This vessel consists of the outer wall 12, connected with the said pipe and an inner wall13, which is connected with a similar pipe 14, open at its lower end and journaled in bearings 14a, secured to cross-beam 15, connected with the tub 1. It will thus be seen that there is a chamber formed between said inner wall and pipe 14, which is to be filled with ice as is also the tub 1.

Stopped in the-cap or cover 7 a is a pipe 16,

of smaller diameter and located within pipe 14, provided with a coupling 17, having a series of radially and upwardly extending pipes 18. These pipes 18 are provided at their upper ends with perforated heads 19, and also with a series of perforated dashers or blades 20, intermediate of their ends. The pipe 16 extends upwardly through a yoke 21, secured to the tub 1, and is provided with a bevel gear wheel 22, meshing with a similar wheel 23 on a shaft 24, journaled in said yoke, and in a bracket 21a depending therefrom said shaft being provided with a crank 25. The gear 23 also meshes with a similar gear 26, secured to the upper end of pipe 14. The upper end of said pipe 16 is secured to a mixing vessel or receptacle 27, of glass or other transparent material, and communicates with a perforated vessel 28, located in the lower partof vessel 27.

' The numeral 29, denotes a pipe located in vessel 27, provided with a perforated nozzle 30, discharging near the top of said vessel. The lower end of this pipe is bent outwardly passing through the vessels 27 and 28, and communicating with acoupling 31 with which is connected a liquid pipe 32, and a carbonio acid gas pipe 33. Connected with pipe 32 is a circulating pipe 34, communicating with the fount 4. f

The numeral 36, designates a water gage, connected by means of pipes 35, with the cooling vessel, by means of which the height of the water in said vessel may be ascertained.

Connected with vessel 10 is a pipe 37 leading to and communicating with pipe 14, for the purpose of equalizing the pressure, and is provi-ded with a stop-cock 38 for allowing air to escape, if desired.

The numeral 36aL designates a pressure gage connected by pipe 35a with the fount and the numeral 47 denotes a removable cap for charging the vessel 12 with water, when it is desired to operate the apparatus in the ordinary manner.

The pipes should be made of block tin and provided with suitable stop cocks and studing boxes whenever necessary, and the fount and cooling vessel should be made of metal and enameled upon the inside. I do not,

however, limit myself to any particular ma- ICO terial composing the parts, nor to any particular manner or method of making or arranging the same, as various modifications may be made without departing from the principle of the invention.

In operation the tub 4is iilled with broken ice, as well as the space between the cooling vessel and the pipe 14. Liquid and carbonio acid gas are then fed from any suitable source of supply to the coupling 31 and from thence they are carried by means of pipe 29, to the mixing vessel 27, escaping through the perforated nozzle 30. At the same time the shaft 24 is rotated by means of a crank or otherwise, and by means of the bevel Wheel 22, and gear 23, the pipe 16 and vessel 27 are also rotated. From vessel 27, the mixed gas and liquid are forced through the perforated vessel 2S,l to pipe 16, and from thence it passes through coupling 17 to the radial pipes 1S, escaping into the cooling vessel,which is also rotated by means of gears 22 and 26, but in an opposite direction to pipe 16. By means of the blades or dashers 20, the carbonated liquid is thoroughly and violently agitated and cooled in a manner similar to that of an ordinary ice cream freezer. From the cooling vessel the cooled liquid passes to the pipe 7, and from thence to the fount, from whence it may be drawn olf for bottlingl or other purposes. By means of the pipe 34, a portion of the liquid in the fount is forced up to the gas pipe, and commingles with the gas therein and is carried to the mixing chamber and sight vessel, ou the principle of an injector, and is then carried back to the fount, so that a constant circulation is kept up.

Having thus described my invention, what I claim isi 1. In an apparatus for carbonatin g liquids, the combination with the tub, the fount having draw-oit pipe stepped in said fount, the liquid vessel located in said tub and connected with said pipe having an inner wall forming a cooling chamber, and the pipe passing through said cooling chamber open at its lower end and connected with said inner wall, of the pipe passing through said pipe provided with a coupling having radial arms with perforated nozzles, the mixing vessel, the pipe located therein; and the gas and liquid pipes connected therewith, substantially as described.

2. In an apparatus for carbonating liquids, the combination with-the tub, the fount, having draw-off pipe, the pipe having perforations in its lower end located in said fount, the liquid vessel located in said tub and connected with said pipe, the cooling chamber or vessel located in said liquid vessel, the rotatable pipe open at its lower end passing through said cooling vessel and connected therewith, the rotatable pipe passing through said last mentioned pipe having a coupling provided with radial arms with perforated nozzles, the mixing vessel connected with the upper end of said pipe, the pipe located therein, the gas and liquid pipes connected therewith and means substantially as described for rotating said rotatable pipes in opposite directions.

3. In a liquid carbonating apparatus, the combination with the tub, the fount provided with draw-oit pipe, the pipe located therein having apertures in its lower end and a perforated cover located above its upper end, the liquid vessel connected with said pipe, the cooling vessel located within said liquid receptacle, the rotatable pipe passing therethrough and connected therewith, the rotatable pipe stepped in said perforated cover passing through said rotatable pipe and provided with radial arms, perforated nozzles and dashers, the mixing vessel connected therewith, the bent pipe located therein, the gas and liquid pipes connected with said bent pipe, the perforated vessel located in said mixing vessel, the cqualizing pipe connected with said liquid vessel, and means substantially as described for rotating said rotatable pipes.

In testimony that I claim the foregoing as my own Ihave hereunto aftixed my signature in presence of two witnesses.

BENJAMIN F. TATMAN.
